Re: Remote IIS 5.x and IIS 6.0 Server Name Spoof
Dear inge_eivind.henriksen@xxxxxxxxx,
The bug here is not in ability to spoof SERVER_NAME, because SERVER_NAME
is untrusted data from Host: request header or from proxy-style HTTP
request (like in case of your example). SERVER_NAME is ALWAYS untrusted
data. The bug here is in the way SERVER_NAME is used in error page
genaration. So, you article should be called something like "Microsoft
IIS error page access validation weakness". If any script use
SERVER_NAME in this way, this is vulnerability of the script itself.
